    - # Outline editor prototype
      - An outline-based markdown editor experiment
      - ### Infuences::
        - Logseq
    	- Tomboy
    	- Bonsai
      -
      - // Seems that I unintentionally implemented quite a chunk of the markdown spec ;)
      -
    - ## Bugs:
      - BUG: last node seems to get trash tags added to it's end...
      -
    - ## ToDo:
      - ASAP: checkbox navigation via `alt-`
        - _might be a good idea to include also TODO/DONE navigation -- not yet sure how to mark undone blocks (i.e. the ones marked with TODO in Logseg)..._
        - toggle with `space`
        - navigation auto-selects first checkbox
      - ASAP: scroll into view is bad...
      - ASAP: mobile browsers behave quite chaotically ignoring parts of the styling...
      - ASAP: need to reach checkboxes via keyboard
        _...not sure how to do this with tab taken..._
      - FEATURE: read-only mode
      - export html
        - embed css
    	- cleanup html
    	- generate ideomatic html (???)
      - FEATURE: `collapse-children:: true` block option -- when loading collapse all immediate children
      - FF: figure out a way to draw expand/collapse bullets without the use of CSS' `:has(..)`
      - a way to make a block monospace (???)
      - codeblock as a block
        _...if only whitespace before/after clear it and style whole block..._
    	_...might be a good idea to do this with codeblock at start/end of block..._
      - Code blocks and bullets:
        - ```
          code
          ```
        - _bullet should be either in the middle of the block or at the first line of code (preferred)..._
      - show list bullet if node is empty but edited... (???)
      - editor as a custom element...
      - Nerd fonts (option???)
      - multiple node selection
      - copy/paste nodes/trees
      - undo
        collapsed:: true
        - delete node
        - indent/deindent
        - edit node
      - auto-shift done blocks to the end of siblings... (option?)
      - FEATURE? block templates...
        collapsed:: true
    	- something like: `TPL: [_]  -- `
          - `TPL:` -- template marker
    	  - `` -- field marker
          - each child node will copy the template and allow editing of only fields
          - not clear how to handle template changes...
      - Q: can we get the caret line in a textarea???
        - _...this will fix a lot of issues with moving between blocks in edit mode..._
      - Q: do we use \\t for indent? (option???)
      - Q: can we place the cursor on item click where it was clicked before before the code expanded?
        collapsed:: true
        - for example
          - #### Click in this line and see where the cursor goes
        - _not sure how..._
      - Q: persistent empty first/last node (a button to create a new node)?
      - Q: should list bullets be on the same level as nodes or offset??
        collapsed:: true
        - A) justified to bullet:
             * list item
             * list item
             block text
        - B) justified to text _(current)_:
             * list item
             * list item
               block text
        - NOTE: this is only a problem if making list-items manually -- disable???
      - empty item height is a bit off...
      - DONE editor: backsapce/del at start/end of a block should join it with prev/next
      - DONE editor: pressing enter in text edit mode should split text into two blocks
      - DONE editor: shifting nodes up/down
      - DONE Q: can we edit code in a code block directly? (a-la Logseq)
      - DONE "percentage complete" in parent blocks with todo's nested
      - DONE `.editor .outline:empty` view and behavior...
      - DONE editor: semi-live update styles
      - DONE do a better expand/collapse icons
      - DONE loading from DOM -- fill textarea
      - DONE focus management
      - DONE mouse/touch controls
      - DONE navigation
      - DONE expand/collapse subtree
      - DONE shift subtree up/down
      - DONE create node
      - DONE edit node
      - DONE serialize/deserialize
      - DONE add optional text styling to nodes
      -
    - ## Refactoring:
      - Plugin architecture
        - DONE basic structure
        - plugin handler sequencing (see: `.setup(..)`)
        - plugin handler canceling
      - DONE Item parser (`.__code2html__(..)`)
        - DONE split out
        - DONE define a way to extend/stack parsers
      - Format parser/generator
        - split out
        - define api
        - experiment with clean _markdown_ as format
      - CSS
        - separate out theming
        - separate out settings
      - Actions -- move user actions (code in `.keyboard`) into methods
      - Move to `keyboard.js`
      - Plugin architecture
        - Q: do we need `features.js` and/or `actions.js`
      - Q: do we need a concatenative API??
    	- `.get() -> `
